INCINERATOR.

Specification of Letters Patent.

Application filed October 6, 1914. Serial No. 865,256.

To all whom it may concern:

Be it known that we, ALEXANDER LEIGH- rox and Hnxnr NORLANDE RU'I'IAN, both of the city of \Vinnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Incinerators, fication.

The invention relates to improvements in incinerators and the object of the invention is primarily to provide an improved form of incinerator wherein garbage or similar material can be effectively burnt and with despatch. I

A further object of the invention is to provide in the incinerator an improved form of furnace presenting a drying arch on which the material to be burnt is suspended for an interval of time prior to being deposited on the grates and while so'suspended subjected to a hot air draft.

A further object of the invention is to provide, in combination with the arch above mentioned, water pipes as a protection to the side of the arch.

A further object of the invention is to provide an incinerator with a plurality of furnaces wherein the products of combustion from the furnaces are all collected on a central flue and are primarily utilized to heat a boiler, and later in a preheater, to heat incoming air afterward directed to the furnaces to support combustion.

\Vith the above and other objects in view, which will become more apparent as the description proceeds the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claim.

Figure 1 represents a side view of the incinerator. Fig. 2 represents a horizontal sectional view through the same, the section being taken in theplane denoted by the line X- Fig. 8. .Fig. 3 is a vertical sectional view centrally and longitudinally through the incinerator, certain parts being shown in side elevation. Fig. 4 represents a vertical crosssectional view through the incinerator. Fig. 5 represents a vertical sectional view through the front end of the incinerator showing the boiler and adjoining parts in side'elevation. Fig. 6 represents a vertical sectional'v-iew through the preheater.

In the drawings like characters of referof which the following is the specithe opposite ends with ence indicate corresponding parts in each figure.

1 represents the walls of the incinerator building which carry a suitable roof 2 and an elevated cement floor 3.

f1 represents the preferably formed material.

The walls are mounted on suitable piers 5 embedded in the-ground.

6, 7, 8 and 9 are similar furnaces located pairs at opposite sides of a central flue 10,

ground floor which is mama Oct. areas.

from pement or similar the flue being provided with a. vertical longitudinally disposed baflie wall 11 as best shown in Figs. 2 and 4 of the drawings.

The flue and also the furnaces are formed from suitable masonry, each of the furnaces opening to the flue through outlet openings 12 reserved in the masonry. The rear end of the flue is closed, save for a clean out door 13 while the forward end inclines slightly downwardly and opens toa suitable brick heating chamber 14, which is in reality a continuation of the main flue. The heating chamber 14 communicates through an opening 15 directly with the interior of a closed brick structure 16 in the walls of which I have mounted a water boiler 17. This boiler can be of any approved type, that shown in the drawings being of the Babcock and Wilcox design embodying in its structure a water boiler 17' and inclined water heating tubes 17 the boiler and supported on suitable bridges 18 provided.

A furnace 19 is located at the end of the boiler chamber and communicates with the same through an opening 20 reserved in the masonry. This furnace is supplied with a grate 21 and fire door 22, and is provided so that the boiler can be heated independently of the flue gases as later described.

23 is a preheater in the nature of a cylinder suitably mounted in the floor 3 and hav-- communicating at the details of the fan as the" action of an induced draft fan is well understood. The fan is operated by an engine indicated-at 29.

The interior of the preheater presents a plurality of spaced vertically disposed heating tubes 30 having their upper and' lower ends mounted in carrying plates 31 and 32 permanently secured to the wall of the chamber. The products of combustion directed to the preheater by the pipe 24 are passed through the heating tubes 30 prior to escaping to the chimney through the pipe 26. The above interior construction of the preheater provides a heating drum 33 between the plates 31 and 32 and around the tubes.

The furnaces 6, 7, 8 and 9 are all identical in construction'and one of them is now described in detail. The furnace chamber in each instance, is approached from the top through a charging hopper 34 which is supplied with pivoted self opening and closing doors 35 and material is placed in the hopper from the floor 3. The'material passed to the furnace through the hopper is designed to fall on the drying arch 36 passing it is to be noticed that there is an opening reserved between the forward end of the arch and the forward wall of the furnace through which, opening the material drawn from the arch by the poker can fall onto th front end of the grate.

41 is a clean out door opening to the under side of the grate.

It is here to be noticed that the opening 12 from the furnace to the flue is located above the arch.

As the forward sides of the arches are very apt to be damaged by the attendant in stoking we have suppliedwatercoils 42 on the forward sides of the arches, these being connected with a water heater heated by the boiler. i

43 represents a suitably mounted, and located water heater connected by means of top and bottom pipes 44 and 45 with the boiler 17.

46 is a return pipe passing from the top of the water heater 43 and 47 is a lead pipe connected with the lower end of the water heater. The pipes 46 and 47 communicate with the coils 42 of the furnace, so that once the water in the water heater 43 is heated by the boiler a circulation of hot water is established through the coils. We have not given a detailed description of the connections between the pipes 46 and 47 and the coils as this is not considered necessary, it

being sufiicient for the purposes of this invent the front faces of the drying arches from being damaged by the stoker.

The drum of the preheater is utilized to heat, to an intense heat, air which is afterward utilized to support combustion in the furnaces 6, 7, 8 and '9. The manner in which this is done is now described: 48 is across flue passing across the heating chamber 14 and having the one end opening to the air and the other end communicating with the casing of a suitably mounted forced draft fan 49, the fan being operated by a steam engine 50. We have not entered into the details of this construction as this forms no part of the invention only in so far as it is utilized in the usual Way to create a forced draft through an air pipe 51 which opens to the interior of the drum of the preheater. A second main air pipe 52 leads from the interior of the preheater drum to the back of the incinerator in a location abovethe main flue. A pair of branch air pipes 53 and 54 pass from the main pipe 52 to the furnaces 6 and '8 opening beneath the grates and a further pair of branch air pipes 55 and 56 lead from the rear end of the main pipe 52-to the furnaces 7 and 9 opening also to the same beneath the grates. According to this construction the air passed through the cross flue 48 is heated primarily by the products of combustion passed into the heating chamber through the flue 10 and is subsequently heated to a high temperature in the drum by the products of combustion passed through the heating tubes of the drum. This air is then forced by the forced draft fan to the pipe 52 by which it is afterward distributed by the branch pipes to the respective furnaces and supports combustionin the furnaces as well as provides a means for drying the garbage or refuse resting on the arches. The engines for driving the fans are operated by steam supplied from the boiler as will readily be understood.

In using the incinerator fires are kindled on the grates of the furnaces and the garbage or refuse is then thrown down onto the arches through the entrance gates. It is primarily dried to a certain extent on the archesand is then raked off by the attendant onto the grates, entrance being had through the stok'ng doors 40. The garbage the intense heat of the furnaces and also preso raked down, in burning, supplies the fire for the further operation of the incinerator. The products of combustion from the various furnaces are collected in the main flue and passed through the heating chamber to a point beneath the boiler and then to the chimney through. the preheater. They are utilized accordingly for heating the boiler and effecting subsequently the circulation of the Water in the coils 42. Further they are used to heat finally to a high temperature the air drawn in through the cross flue 48 and consequently passed to the furnace through the branch air pipes, this heated air not only aiding to support combustion but also effecting a strong hot air draft through the furnaces Which effectively dries the garbage retained on the arches.

What We claim as our invention is In an incinerator the combination comprising a central flue, a plurality of opposing furnaces located on either side of the flue and provided With grates, drying arches elevated above the grates and outlet openings located above the drying arches and opening to the flue, a chimney communicating With the flue, a preheater interposed between the chimney and the flue, means for effecting an induced draft of the products of combustion through the preheater to the chimney, air pipes communicating with the preheater and leading to the furnaces, opening to the same beneath the grates, a cross flue communicating with the atmosphere passing across the central flue, a connection between the cross flue and the preheater and a forced draft fan interposed in the latter connection and designed to effect a forced hot air draft through the preheater and air pipes to the furnaces, as and for the purpose specified.
